pressing F for fullscreen mode in LR buggy Windows 10 / 4k screen

  • Updated 2 years ago

When you press "F" to generate a fullscreen preview of an image in Lightroom it comes to a black screen with Loading...  Now half the time it then gives you the full screen preview.  The other half it continues cycling between Lr and the Loading screen with the only way to interrupt the process is to end task the program.  After about 2-3 minutes of cycling the program crashes itself if uninterrupted.  A Lr process called "Bezel" keeps opening and closing during this time.

My setup is Windows 10 with 4k screen.

Why is this happening Adobe?  It isn't only about Mac in the photo industry.

Haven't seen this on my machine and I'm also on Win10 with a 4k screen - though I do know other problems with 4K... I guess it would be good if you shared your system specs (Help>System Info) so if you are lucky and somebody authoritative replies you can be helped in a better way

I would suspect an old/bad video driver or an unsupported graphics card.

First, if you're on windows, update your video drivers. Determine what video card you have and go *directly to the manufacturers website (nVidia or ATI/AMD)* and download the latest driver.

Just doing Windows Update won't give you the latest and greatest drivers. You must go directly to your card manufacturers website to check for driver updates.

If that doesn’t solve it, go to the Preferences in Lightroom and uncheck “Use Graphics Processor” under the Performance tab and restart Lightroom: https://helpx.adobe.com/lightroom/kb/lightroom-gpu-faq.html

I know how to troubleshoot.  I have troubleshooted this issue on 3 separate Dell Laptops.

2 x Dell XPS 15 9550 machines with 2GB Nvidia Geforce 960M cards with 4k screen I7 6920 cpu

my current one ive again replicated this issue on is a Dell Xeon 1505M v5 running a Quadro M2000M 4GB card. 

I have tried every driver known to man, including Dell ISV drivers and nothing solves it.

It is a fault in your software my friend.  Your software does not like Windows users.

The other problem is constant NVIDIA driver crashes in photoshop no matter the version of driver.  The driver crashes and recovers.

If I turn off graphics acceleration performance becomes worse.

Please address that its your software and not me.

I am a CCNA and MCSE with 15 years in the field.

Regards,

Michael

Which version of Lightroom? Are you in the library or the develop module when this happens? Are you able to reproduce this with a new catalog?

i am able to reproduce this on 3 different dell laptops with different spec.  It happens in develop module.  It happens in any catalogue.  Lightroom CC.

I love how the Adobe guy again fails to recognise a problem and abandons this thread

When the application crashes, what does the detailed crash log say the faulting module is?

It may help if we had both the Photoshop and Lightroom system info. Launch PS and LR and select Help > System Info... and copy/paste the information in a reply (Photoshop's system info has some additional details which may help with this LR issue)

Findings about 4K & spot removal which is an issue with the last version as well.
1. I'm aware of the GPU acceleration issue - that it works faster without it.
2. I found that the main problem of slowness by far is the 4K resolution
3. for example if I do spot removal on 4k on big panoramas of 40000x7000 pixels (280 MP) it takes about 8 seconds between each spot removal click to until I get my mouse control back (this includes black screen flickering back and forth). GPU acceleration off., with GPU Acceleration on its about 13 seconds for each spot removal click, and the detail tab is switched off (noise removal).
4. now the best part is that once I switch to 1920x1080 it is instant yes !! on the same massive file.
5. my spec is Windows 10, Nvida GTX 980 Ti, i7 5960X 8 core 64GB DDR4 everything is on m.2 PCI EXpress NVME and SSDs 
6. my files are Phase one IQ280 - 80MP
7. The slowness is in everything but mostly in spot or local adjustments functions (with the GPU off) the when I do sliders adjustment WB / Exposure I turn the GPU back on and its relatively ok in 4K but in 1920x1080 its super fast.

I have the latest drives from nvidia.

any suggestion will be welcomed.
